Firms decide product speci"cations at the beginning of the game, in which autarky is followed by trade liberalization (whose date is anticipated).

This outcome might be reversed if small country "rms have a strong cost advantage,
transport costs are negligible, or if the large country opens its market before the small one.[+][-]
